Normally we don’t steam the tower; we do so only during major shutdowns for maintenance. There was also one instance when the tower was steamed due to an accident that caused a shutdown

In the event of material removal from each tower, it is necessary to steam the tower before carrying out any work on the equipment or performing welding operations on the tower; this process usually takes 48 hours, with a steam pressure of 0.8 MPA
